Codecademy: JavaScript Lessons- 5- Variables

In this tutorial we will be learning how to write and use variables in Javascript with Codecademy. Variables in Javascript as well as in most programming languages act as placeholders for either values that have or have not been defined.

One way to think of it is like this, your going to a Car Dealership to buy a Tesla Sport cars, you have $80,000 but you don't know just how much your dream car will cost. You can choose to create two variables, myWallet and carCost. Having two variables will allow you to reuse either on throughout your code at any given time for whatever reason. You can subtract both variables to receive specific values
